Abstract
A telecommunications network including a CDMA system and FDMA/TDMA system, both operating in a common frequency range, is disclosed. In an embodiment of the invention, the transmission and reception of narrowband FDMA/TDMA signals on a plurality of radio frequency channels within FDMA/TDMA system is synchronized such that at least one time slot of each TDMA frame on each radio channel is reserved. The transmission and reception of CDMA signals in the CDMA system is then performed during the reserved time slots of each TDMA frame. In an alternative embodiment, complete TDMA frames on each radio channel are reserved for CDMA transmission and reception.
